In reaction of quinoline N-oxide with 2-aminopyridine in the presence of tosyl chloride the substrate undergoes reductive amination into 2-pyridyl(2-quinolyl)an-line, and with 3- and 4-aminopyridines reductive tosylamination occurs to furnish N-tosyl derivatives of the corresponding 3- and 4-pyridyl(2-quinolyl)amines. N-tosyl derivatives of aminopyridines also react along reductive tosylamination pathway.
